SAND-CLEANING MACHINE.

Application filed Apri1`2,

l of Missouri, have invented certain new and p .useful Improvements4 in Sand-Cleaning Machines, of which `the following is a specication, reference being had to the accompanying drawings.

The present invention has for its purpose to provide a machine of this character, wherein a screw conveyor or auger is employed on an inclined plane mounted in a trough or chute including means vfor feed ing water at intervals at one side of the trough or chute, whereby the sand may be propelled throughv the .chute or trough against the water, which washes it,'the sand being carried upwardly and discharged into a wagon, while the foreign matter or dirt and water discharges at the lower end on the ground.` i

Another purpose is the provision of means for sifting the sand, separating thc'larger parts, such as gravel and large stone, prior to feeding it into the chute. Y y

Still another purpose is the provision. of means for shaking or vibrating the sieve, and also having operativevconnections with the conveyor for 'imparting movement to the auger, whereby the process of cleaning l vhinged at 5 and 6to the sieve` and the sides the sand is substantially continuous.

A further purpose consists in the provision of means for swivelly connecting the chute and the shaft of the conveyor', to permit the chute to be raised and lowered, in order to change the inclination of the same, in combination with means for tilting the chute.

A still further purposeis the provision of means for regulating the pump, so as tol govern the supply of water being fed to the chute. l

While the design and construction at present 'illustrated and set forth' is deemed preferable, it is obvious that as a result of a reduction of the inventionV to a more practical form for commercial purposes, the invention may be susceptible of changes, and the right to `these changes is cla-imed,pr`o vided they are comprehended within the scope of what is claimed.

rIhre invention comprises further #features andcombination of parts, as will be hereported stationary.

Referring to the drawings, l designates a frame, which may fit the wagon, so that it v.

may be moved from` one place to another, though .it 1s obviousthe frame' may be sup- Mounted .onthe frame lis a suitable sieve 2 having sides 3, in which the sand to beyy cleaned vmay be deposited. The sieve -is supported lby the. uprights 4 whichv are of the frame l. Itiwill be notedthat 'these supports 4 .are capablel of'being oscillated, j y I therefore causing an oscillatory `movement to be imparted to the sieve. A hopperf extends `downwardly from the sieve, and

has inclined sides, and terminates ina chute 8. lt will be noted that the upper and c v the bevels on the ends of `the uprights 4 at i opposite direction. These bevels permit the -uprights 4 totilt,l when a reciprocating movement` .is 4imparted to `the sieve 2.

"the right are beveled correspondingly 'in the Furthermore the bevelsof the uprights -4 on the vleft in Figure 2 Contact with the Lside ypieces of the frame l, and .thebettom of the sieve Q, thereby limiting the sieve when 0f CheOPPQSte eplellts 4 Will 11i-mit the sier@ when -reciprocated in the opposite dzzrton.,

The bevels stance should the si ve tilt in a direction toward the chute or trough 21, in case'the pitmen 1 4 are disconnected from thecr'anlr shaft, the chute 8 would bear or engage into the chute or trough 21, and may in all probability damage some part of the machine. However due to the construction of the uprights 4, the sieve may at all times be supported, out of contact with the frame of the machine below.

A crank shaft 9 is mounted in bearings 10 `of the frame 1 and has pulleys 11 on its ends.

An additional pulley 12 is also carried by the shaft 9. The cranks 13 of the shaft are operatively connected by the pitman 14 to the sieve, in order to impart an oscillatory movement thereto. A. downwardly inclined trough 15 is carriedY by the sieve, for the purpose of carrying of' all rocks and large pieces, which do not pass through the openings of the sieve. The rocks and large pieces are discharged through 'the openings 16.

A second shaft 17 is mounted in bearings of the sides of the framepl, and pivotally mounted on this shaft by means of the bearings 18 are beams of connecting` pieces 19, which are bolted at 2O to the sides of a chute or trough 21, thereby pivotally mount ing the chute or trough 21, so that it may be tilted upwardly and downwardly. -The ends of the shaft 17 carry pulleys 22, which are operatively connected to the pulleys 11 by means of belts 23, though itis obvious that either one of the belts may be dispensed with if desired. By means of a pulley 24 operatively connected to any suitable source of power by means of a belt 25, power may be transmitted to the crank shaft 9, which will in turn impart movement to the shaft 17.

A bevel gear 26 is carried by the shaft 17, and in mesh with gear 27, which is carried by the shaft 28 of the screw conveyor or auger 29, which is mounted lin the chute or trough 21. The shaft 28 of the screw conveyor or auger is mounted in bearings 30 of the cross pieces at the ends of thev chute or trough 21.

The shaft 28 is also mounted in a bearing, 31

which is carried by the cross piece 32,'-which connects the beams or pieces 19. Suitable collars 33 are mounted on the shafty 17,- to hold the beams or pieces 19 in position., and thereby hold the gears 26 Aand 27 in mesh. By this construction it will be noted that the chute or trough 21 is swivelly mounted, yet the shaft receives revoluble movement, allowing the chute or trough to be tilted up wardly and downwardly, so as to regulate the travel of the sand.

A derrick 34 is mounted upon the frame 1, and journaled upon a shaft l35 of the upper part of the derrick is a pulley 36, which is engaged by a cable 37. One end of the cable 37 is operatively con nected to the chute or trough 21 as shown, while the other portion of the cable is vound about a drum or reel 33, which is rotatable with the stub crank shaft 39, there being a ratchet and pa-wl 40 and 41 for holding the reel or drum in different positions. Gbviously by turning the crank shaft 39, the cable 37 may be wound upon the reel or drum, and thereby tilt the chute or trough,

to different inclined positions for governing` the travel of the sand.

Also carried by the frame 1 is conventional form of pump 42, which obtains the supply of water through the pipe 43, which may be connected to 'any suitable source of supply. A pipe 44 is connected to the pump and is extended and terminates in a portion 45, which is disposed in parallelism tothe chute or trough 21. The portion 45 of the pipc is provided with a plurality of branch 5tubes 46, which enter a supply of water through the side of the chute or trough, for the purpose of thoroughly washing the sand. The shaft 47 of the pump 42 has fixed thereto a friction pulley 48, and loosely mounted upon said shaft is a friction pulley 50, which is operatively connected to the pulley 12 of the belt 49. The pulley 48 is fixed to rotate with the shaft 47, but capable of sliding thereon, and may be moved axially onv the sl1aft47 by means of lever 51, so aste move it into frictional contact with the loose pulley 50, which is belted to the pulley 12. The lever 51 may be held in different adjusted positions by the usual forni of hand gripped operated dog 52, in order to hold the lever in different positions. @bviously by increasing the friction between the twopulleys, the faster the pump will operate,and by decreasing the friction between the pulleys, the pump will operate slower, thereby decreasing the supply of water. The faster the pump operates, the greater of supply and force of the water will be forced through the pipe 44, which is provided with a valve 53, for cutting off the water when the occasion arises.

rllhe sand to be cleaned is agitated in the sieve, the rock, stone, large pieces kbeing discharged through the openings 16 and passed through the chute 15. The sand which passes through the sieve is carried through the hopper, through the shaft 8, and into the chute 21, where the sand is thoroughly washed, the sand being propelled upwardly through the chute and discharged at its upper end into a wagon, 'while the foreign matter, refuse, or dirt together with the water travels downwardly and discharges upon the ground. y

The screw conveyor shaft 29a in Figure 6 has a screw conveyor blade 29b mounted thereon. rIhis spiral or screw blade 29a lcomprises a plurality of sections 30a, which may be casted with the shaft if desired, there being a rectangular shank 2Ob passing through the shaft to prevent the section from .turning, there being a nut 30 threaded on a reduced extension 30d of the shank. 30h, to hold' the section in position. v y
